Thermopride furnace fizzles during cycles
I have a Thermopride, 2 stage NATURAL GAS fired
Condensing Furnace
Model # CHX1-75N
Almost 5 years old
95% Efficiency
Lux products programmable thermostat- Series 602
The issue that we are having is when the furnace has not had enough time to rest in between cycles. It will bring it up to the proper temperature but if is COLD out and it needs to run soon after it shuts down it will start, stop, start, stop start, stop without ever increasing the temp in house. It will go from 62 degrees to 70 without a problem when the thermostat calls for it and run until it raises the 8 degrees needed such as when we are on our way home from work.
If the house temperature is up to what the thermostat calls for and it needs to start relatively soon after it will act up every time. We do not really have a time frame on this but if it needs to kick the heat back on in less than 6-8 minutes it simply will not cooperate. It has not really been too much of an issue to us but at the present time it is still under warranty. (ONLY THE PARTS NOT LABOR)
We live in Ohio and we had temps 2 consecutive mornings that were -8 and -15 and needless to say the furnace does not stay off for long when it is that cold outside. When the temperature is mild 20 degrees and above it works fine. I will call a serviceman more than likely but when you have an intermittent problem you have to get them here when it malfunctions.
Any ideas on what the problem could be? THANKS in advance for your help.
I actually love the furnace as it has cut our gas bills more than half. I haven't even had one over a hundred dollars so far this year and everything in the house is GAS (furnace, water heater, clothes dryer and range)
